Application filed January 14, 1914. Serial No. 812,061.

To all whom it may concern Be it known that I, LEONHARDT SEssLER, asubject of the German Emperor, and a resident of Bottenweiler, nearZumhaus, Bavaria, Germany, have invented an Improved and NovelSeed-Feeding Apparatus for Cultivators with Disks and Elastic Teeth, ofwhich the following is a specification.

The detachable seed feeding funnels as hitherto employed in connectionwith drill barrows required a special construction of the former toallow their attachment to elastic teeth, as well as to the axles of therotary disks; furthermore, special girders had to be provided whichrendered the construction complicated and entailed also other drawbacks.

The deficiencies in question are obviated by making the configuration ofthe hoppers uniform and connecting them with their girders or carriersin a uniform manner, and the covering blades are arranged in such amanner that they may be independently adjusted in height. It is knownfrom practical experience that it is sometimes advantageous to make theposition of the disks dependent upon the profile and the condition ofthe soil, especially, tolet'the upper parts of said disks hang overrearwardly, and for this reason I have chosen as example in the drawinga form of construction in which the vertical cutting angle of the disks,together with the hoppers and the guard plates, may be regulated in aparticularly simple and practical manner.

According to the present invention each funnel is provided at its rearside with an upwardly extending carrier for the covering blade, which inits turn is provided with a longitudinal slot; and at its front side thefunnel has a fork with a slot into which passes a connecting link whichis fastened to the corresponding elastic tooth or to the correspondingdisk axle, so that the connection of any of the funnels with thecorresponding tooth or disk may be effected by merely sliding the forkupon the stationary connecting link and putting a square pin providedfor this purpose through the coinciding holes in the branches of thefork, whereas the adjustment in height of the covering blade is effectedwithin the longitudinal slot with aid of the corresponding fasteningscrew.

To allow of attaching the funnels in the most simple manner attainable,and in consideration of the, perhaps insuflicient skill of the operator,the funnels are provided with spouts at both sides, tubes extending fromthe front, as well as from the rear, may be attached in a veryconvenient way.

In order to make my invention more clear, I refer to the accompanyingdrawings, in which Figure 1 is a side .view of the novel arrangement inquestion; Fig. 2 is a plan of the parts shown in Fig. 1; Fig. 3 showsthe arrangement of the connecting link to an elastic tooth; Fig. 4: is arepresentation of the bow for adjusting the disk axle; and Figs. 5, 6,and 7 are representations of the differently shaped or distorted elasticteeth with the fork middle pieces applied to them.

The seed feeding funnel 1, which is preferably cast is provided at itsrear part with an upwardly extending carrier 3 for the covering blade,this carrier has a longitudinal slot 2; at its front side the funnel hasa fork 4 which is provided with square holes for reception of thefastening pin 5. The fork d incloses either the connecting link 7secured to the disk axle 6 or the connecting link 9 secured to theelastic tooth 8, so that the connection of any of the funnels 1 with theconnecting lugs 7 or 9 may be effected in the same manner.

The top of the funnel 1 (Fig. 1) is provided at the front and the rearends of the same with spouts 10 which have holes 11 into which areintroduced by known means and in a known manner a seed guide pipe 12which extends to the funnel from the front or the rear ends of theapparatus.

To the lower end of the funnel is attached the known dash plate 13 forthe escaping seed, whereby the possibility is offered of conducting theseed into the furrows produced by the disk or by the elastic tooth.

In order to vary the cutting angle of the disk 16 and thus to enable theadjustment of the disk axle, if this shall be necessary, in a slantingposition said axle is guided in a bow 14; provided with slots and setscrews (Fig. i). The leg 15 of the bow 14 has a slot 17, within whichthe axle 6 can slide up or down and can be adjusted by means of setscrews 18, so that the vertical position of the disks, as well as of thefunnel 1 and the dash plates, may be regulated while a clamping screw 19is adapted to whereby the feed secure the parts in their adjustedpositionfle'gcombination, a seed feeding funnel, an up The clampingscrew 19 works against the supporting standard 20.

Having now described my invention, what I desire to secure by LettersPatent of the United States is:

1. In a machine of the class described, in combination, a seed feedingfunnel, an upwardly directed carrier at the rear of said funnel, acovering blade secured to said carrier, a fork at the front side of saidfunnel, rotating means for drilling the soil, a link secured to the axleof said soil drilling means and means for connecting said fork with saidlink of the said soil drilling means, substantially as described.

2. In a machine of the class described, in

Copies of this patent may be obtained for wardly directed carrier at therear of said funnel, a covering blade secured to said carrier, a fork atthe front side of said funnel, a drilling disk for loosening and turningthe soil, a link secured to the axle of said drilling disk, means forconnecting said link and said fork, and means for adjusting the coveringblade in said carrier, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
